octant - An octant is a group of 18, like the number of eggs in a car

An octant is a group of 18, like the number of eggs in a carton or the number of people who hate your golf game.

My golf instructor said, 'You need 18 holes to prove you're a bad golfer.'

The store clerk said, 'We only have 18 eggs left, so you better grab them.'

My brother said, 'You’re in the 18th hole, and you’re still not good at this.'
